使用输入流写一个对象

这个不知道算是代理模式还是装饰者模式，不过本人认为更像是一个代理模式，继承了outputstream类，但是不用实现它的方法，而是另添加一个方法，可以直接写入一个对象

package io.proxy;

import java.io.Serializable;

public class User implements Serializable {
private String account;
private String password;
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

package io.proxy;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

import com.alibaba.fastjson.JSONObject;

public class FreshbinOutputStream extends OutputStream {

private FileOutputStream out;

public FreshbinOutputStream(String filePath) throws FileNotFoundException {
this.out = new FileOutputStream(filePath,true);
}

public void write(Object user) {
try {
String jsonstr = JSONObject.toJSONString(user);
out.write(jsonstr.getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

public void close(){
if(out != null) {
try {
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

@Override
public void write(int arg0) throws IOException {
// TODO Auto-generated method stub

}
}

package io.proxy;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class Test {

public static void main(String[] args) {
User us1 = new User();
us1.setAccount("freshbin");
us1.setPassword("123");

FreshbinOutputStream fos = null;
try {
fos = new FreshbinOutputStream("h:/test/test.txt");
fos.write(us1);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
fos.close();
}

}
}
